only do it g and h

5. In each part, determine whether the given vector is in the span of S. (a) (2, -1, 1), S = {(1, 0, 2), (-1, 1, 1) } (b) (-1, 2, 1), S = {(1, 0, 2), (-1, 1, 1) } (-1, 1, 1, 2), S = {(1, 0, 1, -1), (0, 1, 1, 1) } (2, -1, 1, -3), S = {(1,0, 1, -1), (0, 1, 1, 1) } -x3 + 2x' +3x +3, S= (x3+x' +x+1,x' + x+1,x+1} 213-x2+x+3, S= (x+x'+x+ 1,x' +x+ 1,x+1 } (h)
